No Wifi Network about mclighting HOT 1 OPEN

When you flashed the sketch to your board, was the board new or did you erase all flash contents (not just the sketch) when uploading the new firmware to the board? You want to make sure you "Erase All" or old wifi settings that are stored on the board might be use again after uploading the new program. This is particularly true if the library version is updated. I found that I could get the firmware to compile with the wrong combination of libraries, (old Wifi manager with old ESP8266 library) but things wouldn't work right (like being able to save your wifi credentials). So, make sure you're on all the right library version, as called out in the Read.me.
